SPECIFICATION forming part of Letters Patent No. 765,429, dated July 19, 1904.

Application filed .ipril 2,1903. Serial No. 150,816. No model.)

To a. whmn Lil; may concern:

Be it known that I, HOBERT J. HURD, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Paper-Tube- Rolling Machines, of which the following is a specification.

My invention relates to paper-tube-forming machines; and it consists in certain improvements to be more fully set forth in the accompanying specification, whereby an increased output and a more economical production of paper tubes is effected.

To enable others to understand my invention, reference is had to the accompanying drawings, in which Figure 1 represents a plan view of the machine, showing a section of paper of which the tube is formed on the feeding-table. Fig. 2 is a side elevation of the machine looking in the direction of arrow 6, Fig. 1. Fig. 3 is'a side elevation of the machine looking in. the direction of arrow f of Fig. 1. Fig. 4 is a rear elevation of the machine, broken view of the paste-discharging pipe looking in the direction of arrow 9 of Fig. 1. Fig. 5 is a sectional elevation of the machine on line it of Fig. 1. Fig. 6 is an enlarged detailsectional view of the rotating arbor-carrying head and its case or housing, broken View, partly in section, of the tube-forming arbors, broken view of the tube-ejecting rack, sectional view of their driving-pinions, broken sectional view of the driving-gear for said pinions, sectional view of the segmental pinion and notched disk forming part of the mechanism for operating the arbor-rotating head, and broken sectional view of the machine-frame for supporting the case or housing for said head. Fig. 7 is a detail view of the segmental pin- .ion connected with the rotating head. Fig.

8 is a detail view of the lower arbor-support and the center operating-lever, broken view of the gear carrying the'cam-plate for operating said lever, and broken view of the lower arbor engaged by the center. Fig. 9 is a broken detail end elevation of the paste-rolls, sectional view of one of the tube-forming arbors, showing a section of paper in readiness to be wound about said arbor, sectional view of the segmental wiper and its shaft, said wiper in its normal position in readiness to guide the paper about the arbor. Fig. 10 is a view similar to Fig. 9, showing the wiper at a standstill with the last flexible finger engaged with the tube. Fig. 11 is a detail view of one of the arbors in its elevated tube-ejecting position, broken view of the tube-ejecting rack with its finger engaging a movable collar on said arbor, broken view of a tube being ejected from the arbor. Fig. 12 is a detail side elevation of the paper-clamping finger in its extreme outer position in readiness to be carried forward, broken view of the paper-feeding slide to which said finger is pivoted, broken view of the lever operating said slide and finger, and broken view of the paper-feeding table. Fig. 13 is a view similar to Fig. 12, showing the slide and clampingfinger in its extreme forward position with the finger released from contact with the paper and in readiness for its backward travel. Fig. 14 is a modified detail broken view of one of the tube-forming arbors, broken sectional view of the rotating head, and sectional view of the arbor-pinion.

Its construction and operation are as follows:

1 represents the base of the machine; 2 and 2*, the uprights.

3 is the main driving-shaft, carrying on its outer end the driving-pulley 4 and the handwheel 5.

6 is a jack-shaft driven from the main shaft through the medium of the pinion 7 and the large gear 8. v(Seen more clearly at Figs. 3 and 4.)

9 and 10 are paste-rolls, driven through the medium of the gear 11 on shaft 6, intermediate gear 12 on stud 13, and gears 14 and 15, mounted on the journals of said rolls. The

lower and larger of these rolls has a portion of its periphery cut away, so as to let go of the paper as soon as the end of the same is properly engaged by the tube-winding arbor presently to be more fully explained. entire surface of the upper roll and that portion of the lower roll which operates in conjunction with the upper roll to carry the pa- The IOO

per along is covered with fine corrugations to hold the paste discharged from the supplypipe 16, which paste passes over the rolls and is discharged into the pan 17. (Shown in sectional view at Fig. 4 and broken View at Fig.

of theretainingscrews 22 and 23, whose heads are let into the inner ends of said journals. These screws, in conjunction with the shouldered portions 18 and 19 of said arbors,. will insure a firm anchorage for the arborsfl The object of this enlarged detachable journal for each of the tube-forming arbors is for convenience in changing the arbors for th-ediifer'ent sizes of tubes required, especiallyj in the manufacture of tubing for paper shot-shell. In removing the arbors all that is necessary is to insert a screw-driver through the hole A when an arbor is in an upper position and remove the retaining-screws and withdraw, the arbor from its journal. Therefore it'makes no difference, so far as the rotatable feature of the arbor is concerned, whether the end of the arbor is detachably secured to an enlarged part to form the journal or the inner, end of the arbor is enlarged, as shown at 18", Fig. 14. These journals are rotatably mounted in the head 24, which head is in turn also rotatably mounted in the case or housing 25, secured to the side frame 2 of the machine. (Seen also at Figs. 1, 2, 3, 4, and 5.) 26 and 27-are pinions keyed on these jou rnals, whose sides are embraced by the outer face of said head and the shoulders and 21 of said journals. The inner ends of these journals are threaded, and on these threaded ends are the adjusting-nuts 28 and 29. 30 and 31 are washers placed between said nutsand a shouldered portion of said journals, which washers are pinned to the journals, so that when said journals rotate the nuts and washers will turn in unison therewith, and thus prevent the nuts working loose.

The rotatable head 24 is rigidly mounted on the enlarged portion of the screw, bolt, or shaft 32, whose head 32 engages a shouldered portion of said head, so as to operatively retain the same within the housing 25. 33 (see Fig.

2 and also detail View Fig. 7) is a segmental pinion reciprocally mounted on the projection 25, Fig. 6, 2 of said housing. This pinion through the medium of its arm 33 supports the'stud 34, projecting from said arm. The portion 32f of the stud 32 is rotatably mounted in said housing and has rigidly secured to;

its outer end the plate 35, provided withthe notches 36.

37, Fig. 2, is a pawl mounted on the stud 34, which pawl is adapted to alternately engage with said notches and rotate the head 24 within its housing for the purpose presently to be described.

The segmental pinion 33 is actuated by means of. the face-cam 38, mounted on the jackshaft 6, Figs. 2 and 4.

39 is a stud which supports a double-arm lever, whose short arm 40 is adjustably connected to the sliding block 41 of said cam. while the long arm 42 carries at its outer end the toothed segment 43 to register and drive the segmental pinion 33.

The toothed segment 43 has an oscillating movement that alternately rotates the head 24 through the medium of the segmental pinion 33 and the alternate engagement of the pawl 37 with the notches in the plate 35, so that when the paper is being wound on one of the tube-rolling arbors the other arbor is in an upper and diametrically opposite position. WVhen the arbors are thus located in vertical alinement with each other, the head 24 is temporarily locked against rotation while a tube is being rolled, and this is accomplished by means of the bolt 44, Figs. 4 and 6, alternately engaging the notches 45 and 46, Fig. 6, diametrically located in the said head 24. This locking-bolt is timed to operate in either of said notches, as the case may be, by means of the slide-bar 47, Figs. 2 and 4, operatively supported in the bracket 48, secured to the base or bed of the machine. The lower end of this bar carries the roll 49, adapted to be engaged by a cam lug or projection (not shown) in a recess inthe face of the gear 50, which gear is mounted on the shaft 6. The locking-bolt 44 is operatively mounted in the tailpiece 25 of the housing 25. 51 is a screw which connects the upper end of the slide-bar 47 with the said locking-bolt, so that when the rotatable head, carrying the arbors, is about to be turned the slide-bar .47 will be actuated downward to withdraw said bolt from the notch .in-said head with which it was engaged, and thus release said head. so that it may be partially rotated by means of the mechanism before described. 52 is a retractile spring which operates to carry said bolt up to engage said notches independent of the sliding bar 47.

The arbors, as before mentioned, are anchored in rotatable bearings located in the rotatable head 24. Consequently these arbors rotate with their bearings. The pinions 26 and 27, mounted on these bearings, are alternately broughtintoengagementwith theintermediate gear 53, mounted on the inner end of the short shaft 54, journaled in,the upright 2. The outer end of this shaft carries the pinion 55. 56 is another intermediate gear, which connects said pinion with the driving-gear on the shaft 6. Therefore by means of this arrangement the pinions connected with the tube-arbors are alternately registered with the gear 53, so that said arbors will be rotated while in their lower ortube-forming position,

while the other or upper-positioned arborwill, being disconnected from said gear, remain stationary.

The outer end of thearbor engaged in tuberolling is supported by the longitudinally-operating center 57, mounted in the housing 58,- Figs.- 3 and 8. 59 is a pivotally-supported lever whose upper forked end engages with the pin 60, projecting up from said center; The opposite end of this lever carries the roll 61, adapted to engage with the cam projection (not shown) located on the inner face of the plate 61 of the gear 14:. The movement of this lever is so timed with respect to the revolving feature ofthe arbors that when one of said arbors is in operation the center will support its free end and when the tube is rolled and the arbor is ready to be revolved the center 57 is automatically withdrawn.

62, Figs. 1, 5, 9, and 10, is a segmental wiper, roll-presser, and paste-scraper having the flexible fingers or brushes 63 inserted in its periphery. This wiper is. rigidly mounted on the shaft 64:, which shaft is journaled in the boxes 65, secured to the side frames of the machine. This combined wiper, presser and scraper, whose purpose will presently be more fully explained, is reciprocally operated by means of the vertical face-cam 66, (seen at Fig. 4,) mounted on the jack-shaft 6.

67 (see also Fig. 3) is a short lever pivoted by one end to the stud 68 of the bed, while the other end is pivotally supported in one of the forked ends of the vertical connectingrod 69. Midway of this lever isthe roll 70, which engages with said face-cam 66. The upper forked end of the connecting-rod 69 is pivotally connected to the arm 71 of the combined wiper. presser, and scraper shaft 64. The mechanism thus described will give a reciprocating or oscillating motion to the said wiper. As soon as a complete tube has been formed on the lower arbor, as before mentioned, then this arbor is revolved into the upper position, with the tube still on it, and while a tube isbeing formed on the other arbor the completed tube on the upper arbor will be ejected therefrom in the following manner, viz: 72 and 73, Figs. 4, 5, 6, and 11, are grooved collars loosely mounted on the tube-forming arbors, and 7 4 (see also Fig. 1) is a rack carrying on its inner end the collar 75, having thefinger 76, adapted to register with the grooved collar on the upper arbor,

brought down to grip the paper.

shaft mounted in this bracket, which carries 1 at its lower end the pinion 84 to register with said rack, and at its upper end it carries the horizontal gear 85 to register with the upper tube-ejecting rack 74. This rack has a longitudinal hole formed therethrough and is adapted thereby to slide freely on its supporting-rod 86.

87, Figs. 1, 2,3, and 5, is the table on which the square of paper 88 (shown by dotted lines at Fig. 1) is placed, this paper being of its proper size necessary to make a finished roll. 89 is a slide operatively working in said table. 90 is the feed-clamping finger pivotally supported on the pin 91, located in the projection 92 of the slide 89. 93 is a link pivotally supported on the pin 9% of the toe 90 of said finger and the pin 95in the upper end of the vertical lever 96. This lever is pivotally supported in the bracket 97, with its lower end pivoted to the outer end of the horizontal lever 98. The forked end of this lever is fulcrumed on the jack-shaft 6 through the medium of'the square block 99. 100, Fig. 5, is a roll on the vertical face of this lever, which roll engages with the vertical face of the cam 101. (Shown also at Fig. 4E.) The mechanism just described operates and controls the movement of both the slide 89 and the finger 90.

This slide is always under a spring tension as follows: 102, Fig. 1, represents tension-rods operating transversely in the table 87, whose free ends bear against the gib 103 of said slide. 104 is a cross-bar which connect the outer ends of said tension-rods. 105 is a tension-adjusting screw passing through this cross-bar and whose threaded end is adjustably connected to the table. 106 is a tension-spring located between the head of said screw and said crossbar. By this means the proper tension is exerted againstsaid slide forthe purpose presently to be explained. It will be understood that the upper surface of the slide projects a trifle above the upper surface of the table in order to place the paper fully under the control of the feed-clamping finger.

At Figs. 1, 2, 3, 5, and 11 the finger 90 is in its extreme outer position, with its free end The movement of the lever 90 in the direction indicated by the arrow 2' (shown at Fig. 5) will carry the slide and finger forward until the forward end IIO of said paper has entered into the bite of the ver will begin to retreat.

ance olfered to its backward movement. Consequently the finger will turn on its pivotal support (see Fig. 13) until the stop 90 of said finger strikes against the projection 92 of the slide.

open position. When this takes place, the

slide will then be under full control of the lever 96, and said slide and its linger will be This stop will limit the upward move ment of the finger and determine its extreme tension on the slide will also hold it-against a forwardmovement until after the finger has been brought down and reengaged with the slide, whereupon the slide, finger, and paper will be carried forward toward the paste-rolls. The pivotal points of the link 93 on the finger and lever are so positioned with respect to the pivotal support of the finger on the 'projection 92 of the slide as to give a togglejoint effect in the grip of the finger on' the slide.

107, Figs. 1 and 5, represents narrow strips of metal adapted to form a bridge between the lower paste-roll andthetube-forming arbor to support the paper in transit. One end of these strips or bars rests in the grooves m of the lower paste-roll and at the bottom of said roll, vhile their opposite ends are arranged in' close proximity 'to one of the tube-forming arbors when in its lower position. The central portions of these bars are attached to the lower rails of the'cross-piece 108, the ends of which rails are supported in the side frames of the machine. 109 represents another series of bars or strips of metal attached to the upper rails of the cross-piece 108. One end of these bars registers with the circumferential grooves 11., formed in the upper paste-roll 19. These upper and lower bars are quite close together near the pasterolls, but diverge from each other as they approach the tube-forming arbor, and between these series of upper and lower bars the paper is fed to said arbor.

110 is a guide for the edge of the paper adjustably mounted on the table 87 and is shown bridge until its forward end (see also Fig. 9)

passes under the rapidly-rotating arbor 19 and above the upper one of the series of flexible fingers 63 of the segmental wiper 62.

Then this wiper is carried up in the direction of arrow 0, and the several flexible fingers thereon will assist in folding the paper around the tube-forming arbor, or, in other words, will guide and maintain the end of the paper in the proper direction to form the tube. The last finger, .63, is reinforced by other and shorter flexible fingers '63 and 68, as this feature is thought to give a better result, although a single and thicker finger could be used. WV hen, therefore, the segmental wiper-frame 62 has rotated far enough to bring the last flexible finger, 63, firmly in contact with the tube being formed, the said wiper-frame will halt, (see also Fig. 10,) while the arborwill still continue to rotate. The pressure of this last linger will cause the paper to wind evenly about the arbor and smooth out any wrinkles that would tend to form. It also forces out and away from the forming-tube all surplus paste, so that when the tube is completed both its exterior and interior surface will be smooth and even. Being thus held firmly against the arbor during the process of winding the tubes are all wound of exact diameters, which is an important feature in forming tubes for paper shot-shells. WVhen the tube is completed on the lower arbor, said arbor and wiper will begin to retreat simultaneously, the arbor in the direction of arrow p, Figs. 3 and 5, to an upper position and the wiper toward its lower or normal position, and when the second arbor is in the winding-field the wiper is ready to move upward. In other words, the segmental wiper follows the first on retreating arbor, and the second on approaching arbor follows the wiper and all move synchronously. While a fresh tube is being formed on this second arbor, the mechanism for operating the rack 74 is brought into action for ejecting the previously-formed tube from the upper arbor, as shown at Fig. 11.

The construction of the machine is such that it is continuous in its operation. In other words, it is so constructed that it can be adjusted so no time is lost by one part waiting until after an important operation is being performed by another part of the machine. Machines have been constructed where the tube-winding arbor remains in the same position, and therefore the paper-feeding mechanism must halt until after the finished tube has been ejected from the arbor, while in my construction the tube is being ejected outside of the winding-field and during the time that the winding operation is still going on. This reversible feature of the tube-forming arbors enables the paper-feeding mechanism to operate continuously, for when the paper is between the paste-rolls, as before mentioned, the feed-clamping finger and slide are retreating and by the time the section of paper within the bite of the feed rolls has passed therefrom another section has entered. So with respect to the tube-forming arbors, as

'; soon as the arborenters the winding-field the paper justdischarged from the paste-rolls is takenup by said arbor. It Will thus be readily seen that as the machine is capable of being run at higlf'speed this continous operation must greatly increase the production and lessen the cost. Y

The segmental wiper has many advantages over one of concentric form. With this latter form of wiper it is" necessary to move it bodily away from the tube-forming arbor as soon as a tube is formed and carry it down and below said arbor, so as not to interfere with an incoming strip of paper about to en' gage the arbor. These motions require more or less complex mechanism to carry them out. With my form of wiper it simply oscillates back to its normal position by the same simple mechanism that effected its forward movement.

In machines of this character it is customary to employ a presser device adapted to be brought against the tube while being rolled, so as to form the same true and even and also to remove the surplus paste and to operate this device independent of the wiper. This, too, requires extra mechanism to operate it. I combine both a wiper to start the paper around the arbor and a presser and pastescraper in one and the same tool. I

While I show and have described an arrangement of cams, levers, &c., for operating the vital features of the machine, I hold myself at liberty to deviate therefrom in order to produce the required eflfect by substantially the same or other well-known and equivalent means.
